Literally?

I saw The Interpreter last night and I enjoyed it, but here's the thing. I know that Nicole Kidman's character is somewhat mysterious and that she's hiding parts of her past and all, but is she meant to be literally hiding them behind her hair? If not, perhaps a barrette would help. Or maybe one of her multi-lingual colleagues could catch her in the U.N. ladies' lounge and show her how to use those pony-tail elastics to greater effect.
